 (No. 22) ; Dr. Hepites (No. 25) will co-operate, using an instrument 

 received from Dr. Tacchini ; whilst Dr. J. Hann (No. 26) replies that he 

 is establishing the Ehlert type of pendulum, and later may also use ours. 

 Co-operation may be expected at some future time from Professor G. E.

 cannot be expected. 



From the remainder replies have not yet been received. 



II. Records of the Gray -Milne Seismograph. 

 By John Milne, F.R.S., F.G.S. 



The first of the above seismographs constructed in 1883, partly at the 

 expense of the British Association, still continues to be used as the 

 standard instrument at the Central Observatory in Tokio. 



I am indebted to the Director of that institution for the following 

 records. The records with which they are continuous will be found in 

 the 'Report of the British Association' for 1895, p. 115.
